Briefly describe some of the differences between cetaceans of the Suborder Odontoceti (toothed whales) with those of the Suborder Mysticeti (baleen whales)

Question

What will be an ideal response?

Answer 1

Cetaceans or whales of the Order Cetacea can be divided into the suborders Odontoceti and Mysticeti based upon the presence of teeth or baleen, respectively. In addition to having teeth for holding onto and orientating captured prey, toothed whales also have one external nasal opening or blowhole, while baleen whales have two. Both suborders rely upon echolocation to communicate and to find prey, but the ability to use sound appears to be better developed in the toothed whales. Toothed whales mostly feed upon fishes and larger invertebrates such as squids, while most of the baleen whales, with the exception of gray whales, feed upon zooplankton and smaller fishes. Most of the toothed whales, with the exception of sperm whales, which can reach 15-m (50 ft.) in length, are typically smaller than most of the baleen whales.
